A GFCI constantly monitors current flowing through a circuit. If the current flowing into the circuit differs from the returning current, even by a very small amount, the GFCI interrupts power in a fraction of a second.  GFCI's are intended to prevent electrical shock, electrocution and burns by shutting down the current before it can cause serious injury or death.  This project deals with the type of GFCI that's integrated into an electrical receptacle.  Protection like this is especially important for electrical equipment located near water.  The National Electrical Code requires GFCI receptacles in these areas:

  • Outdoors
  • Bathrooms
  • Garages
  • Kitchens
  • Crawl spaces and unfinished basements
  • Wet bar sinks
  • Laundry and utility sinks
